[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-12 This utility model provides a technical solution: a water-electricity separation type water feeder, comprising: a water tank 1, a water storage cover 2, a controller 3, and a water outlet 4. The water outlet 4 is located on top of the water storage cover 2, which is detachably connected to the top of the water tank 1. The controller 3 is detachably located below the water tank 1 and contains a drive component. A receiving chamber column 11 extends downward from the bottom of the water tank 1. The controller 3 has a receiving hole 31 corresponding to the receiving chamber column 11. A pumping chamber is located above the receiving chamber column 11, and a rotating component is rotatably mounted within it. A transmission component is located below the rotating component within the receiving chamber column 11. The drive component can drive the rotating component to rotate synchronously via the transmission component, thereby pumping the liquid in the pumping chamber to the water outlet 4. The water tank 1 has a receiving chamber column 11 extending downward from the bottom, and the controller 3 has a receiving hole 31 corresponding to the receiving chamber column 11. The water tank 1 and the controller 3 are detachable and completely physically isolated, preventing liquid in the water tank 1 from entering the controller 3 and affecting the drive component within it.

[0032] Furthermore, in order to enable the rotating component to be rotatably installed and connected in the pump liquid chamber, it also includes a water pump shaft 12, a water pump bracket 13, and the rotating component is a water pump rotor 14. The water pump bracket 13 is detachably installed above the receiving cavity column 11. One end of the water pump shaft 12 is connected to the bottom of the receiving cavity column 11, and the other end extends out of the receiving cavity column 11 and is connected to the mounting hole 131 on the water pump bracket 13. The water pump shaft 12 is sleeved with the water pump rotor 14, and a transmission component located in the receiving cavity column 11 is connected below the water pump rotor 14.

[0033] Furthermore, such as Figure 9As shown, the drive unit includes a wire frame 36, which has a notch 361 for fitting outside the receiving hole 31. The wire frame 36 is connected to a coil 362, a control PCBA board 363, and a Hall sensor 364. The control PCBA board 363 is connected to the Hall sensor 364, and the coil 362 is connected to the control PCBA board 363 and the Hall sensor 364. The Hall sensor 364 is located outside the notch 361 and opposite to the coil 362. The transmission component is a magnet 15, which is located inside the notch 361 and fitted outside the water pump shaft 12. Magnet 15 serves as the rotor, and coil 362 serves as the stator. When current passes through these coils, a magnetic field is generated. Hall sensor 364 serves as a position sensor. After installation, Hall sensor 364 is fixedly connected to coil 362. Hall sensor 364 is used to detect the position of rotor magnet 15 in real time. Control PCBA board 363 is connected to Hall sensor 364. Control PCBA board 363 and Hall sensor 364 form a circuit board (containing Hall sensor) that can generate a magnetic field. Coil 362 is soldered to the bottom of control PCBA board 363. Control PCBA board 363 receives the signal from Hall sensor 364 and then decides which set of coils to let the current flow through. The magnetic field generated by coil 362 changes, similar to the principle of a brushless DC motor, which can cause magnet 15 to rotate. The magnetic field generated by coil 362 causes magnet 15 to rotate. The lower end of water pump rotor 14 is connected to magnet 15. The rotation drives the rotating part, i.e., water pump rotor 14, to rotate synchronously, so as to pump the liquid in the pump chamber to the outlet 4.

[0034] When controller 3 malfunctions, the water tank 1 and controller 3 can be quickly separated for independent disassembly and replacement of the wiring harness. Liquid flows through the rotating parts but not the driving parts, achieving water-electricity separation and effectively preventing the liquid from becoming electrified. Controller 3 is located at the bottom of water tank 1, physically isolated, achieving dry and wet separation between water tank 1 and controller 3, ensuring the stability of the pet water feeder.

[0035] Furthermore, such as Figure 1 and Figure 6 As shown, it also includes filter cotton 5 and a top cover 6. The water storage top cover 2 has a first groove 21 with multiple first through holes 22 on the first groove 21 to allow liquid to flow into the water tank 1. The filter cotton 5 covers the multiple first through holes 22. The top cover 6 is positioned above the filter cotton 5 and has multiple second through holes 61 to allow liquid to flow downwards. The filter cotton can filter impurities in the water on the water storage top cover 2, thus filtering the liquid flowing into the water tank 1 and protecting the water quality of the water tank 1.

[0036] Furthermore, such as Figure 5 and Figure 7As shown, the bottom of the water pump bracket 13 is provided with a first buckle 132, and the bottom of the water tank 1 is provided with a second buckle hole 16 that is connected to the first buckle 132. The first buckle 132 and the second buckle hole 16 are connected to each other, so that the water pump bracket 13 can be detachably installed on the upper part of the receiving cavity column 11.

[0037] Furthermore, in order to form the pump fluid chamber, such as Figure 5 and Figure 7 As shown, the bottom of the water pump bracket 13 is provided with a first chamber 133, and the bottom of the water tank 1 is provided with a second chamber 17. The first chamber 133 and the second chamber 17 form a relatively sealed space. The first chamber 133 is fitted outside the second chamber 17 to form a pump liquid chamber. The center of the first chamber 133 at the bottom of the water pump bracket 13 is connected to the mounting hole 131. Both the first chamber 133 and the second chamber 17 are in the shape of a "6". The top of the water pump bracket 13 is provided with a first water outlet pipe 134. The non-center part of the first chamber 133 or the liquid pumping point is connected to the first water outlet pipe 134. The first water outlet pipe 134 is fitted with a second water outlet pipe 41 connected to the lower end of the petal-shaped water outlet 4. When the blades on the water pump rotor rotate, the water in the relatively sealed space of the pump liquid chamber is pumped into the first water outlet pipe 134 due to pressure. The liquid flows out from the petal-shaped water outlet through the first water outlet pipe 134 and the second water outlet pipe 41, and then falls into the water storage cover 2 for pets to lick.

[0038] Furthermore, it also includes a filter screen 135, which is positioned above the water pump bracket 13. The filter screen 135 serves to filter and prevent impurities from entering the pump fluid chamber. The pump fluid chamber is a relatively enclosed space, and impurities such as pet hair may enter the pump fluid chamber. The filter screen 135 can only filter hair and other impurities above the pump fluid chamber.

[0039] Furthermore, it also includes a water pump bracket cap 136. A mounting part 137 is provided above the water pump bracket 13, and a mounting hole 131 is provided on the mounting part 137. The water pump bracket cap 136 is installed and connected to the mounting part 137. The water pump bracket cap 136 is located above the filter screen 135. The filter screen 135 is provided with corresponding through holes and notches so that the mounting part 137 and the first water outlet pipe 134 can extend out. The area of ​​the water pump bracket cap 136 is larger than the area of ​​the through holes. The function of the water pump bracket cap 136 is to fix the filter screen 135 and prevent the filter screen 135 from falling off the mounting part 137.

[0040] Furthermore, such as Figure 3-4 As shown, the bottom of the water tank 1 is provided with two auxiliary positioning posts 19, and the controller 3 is provided with positioning holes 38 that match and are installed on the auxiliary positioning posts 19. The controller 3 can be detachably installed on the bottom of the water tank 1. The two can be detached and installed through the positioning posts and positioning holes. The water tank 1 can be lifted at any time, and the water tank 1 and the controller 3 can be disassembled.

[0041] Furthermore, the outlet 4 is a petal-shaped outlet 4.

[0042] Furthermore, such as Figure 1 As shown, the controller 3 also includes a front shell 32, a bottom shell 33, a main board PCBA 34, and a battery 35. The front shell 32 and the bottom shell 33 are detachably connected. The main board PCBA 34 is connected to the battery 35. The main board PCBA 34, the battery 35, and the wire frame 36 are all located within the accommodating space formed by the front shell 32 and the bottom shell 33.

[0043] Furthermore, the controller 3 also includes a Type-C charging board PCBA37, which connects to the motherboard PCBA34 and the battery 35. The Type-C charging board PCBA37 has a Type-C interface and is located in the receiving space formed by the front shell 32 and the bottom shell 33. The controller 3 or the front shell 32 has a functional hole that exposes the Type-C interface, through which the battery 35 can be charged.

[0044] Furthermore, the water tank 1 is made of a light-transmitting material.

[0045] Furthermore, such as Figure 2 As shown, the controller 3 or the bottom shell 33 is equipped with silicone feet 331, and the water tank 1 has support legs 18 at its four corners. The bottom of the support legs 18 is at the same horizontal line as the bottom of the silicone feet 331. The controller 3 is housed in the space formed by the four support legs 18. There are six silicone feet 331, located above and below the bottom shell 33. The three upper silicone feet 331 are evenly spaced, and the three lower silicone feet 331 are also evenly spaced. The silicone feet 331 can absorb shock. At the same time, the support legs 18 are located at the four corners of the water tank 1, so that the controller 3 is housed in the space formed by the four support legs 18. The overall product looks beautiful and saves space.

[0046] Furthermore, a distance sensor 341 for sensing water dispensing is connected to the mainboard PCBA34. The controller 3 or the faceplate 32 has an exposure hole for the distance sensor 341. The distance sensor 341 can be an existing 5.8GHz microwave radar module sensor. When a pet is detected approaching, the distance sensor senses the approach and energizes the control coil 362. The magnetic field generated by the coil 362 causes the magnet 15 to rotate, which in turn drives the rotating component, i.e., the water pump rotor, to rotate synchronously, pumping the liquid in the pump chamber to the outlet 4. The mainboard PCBA34 also has an existing timing device that can control the energization of the coil 362 to rotate the magnet 15 at regular intervals, providing both sensing-based and timed water dispensing modes.
